  • The effect of silver ions and nanoparticles on biofilms and planktonic cultures of Nitrosomonas europaea

    Creator:
    Giska, Jonathan R.
    Abstract:
    Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-­‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...

  • Effect of plant surface area on organic carbon removal in wetlands

    Creator:
    Kuehn, Elaine Jinx
    Abstract:
    This study investigated the effect of plant surface area (plant density) on the efficiency of organic carbon removal in a bench-scale constructed wetland. Constructed wetlands are commonly assumed to be biofilm reactors in which organic carbon removal occurs primarily through sedimentation and aerobic degradation by attached microbial biofilms. In conventional...
